Please Note:
1,      If you have not a good DAC or good source, only plan to use with the PC soundcard or  cell phone, this product is not suite you.
2,      For get the product best performance, you must connect with a good balanced source ,good balanced headphone  and hi-end speaker.

3,      The metal remote need assemble two AAA battery by customer because the either DHL and UPS limit shipping by plane.

The unit applied input short design but can disable:

         The unit  had design the analog idle input short circuit for avoid the disturb between different sources.
         This design also applied in a lot high end
brand devices.
         The working theory : 
Without the idle input short circuit ,if the input 5 and input 4 had connect two extra DACs,  while users select the either input 5 and input 4 , the another input signal will fire through the circuits and mix  into the using signal, even though this signal is  weak  but still can degrade on the sound quality.
          With the idle input short circuit function : if user select either the input 5 and input 4, the another input signal will short circuit then no any signal fire through circuits , can keep the sound quality had not degrade.

         Below case users don't want the idle input short circuit function, users can open the chassis, pull off the jumpers of the proper input channels, please note must pull off of left and right channels together :
        1, The same extra source not only connect the
unit analog input, but connect with other amps simultaneity.
        2, The same extra source connect to the
unit different inputs  at simultaneity.
